Explanation: This stunning group of galaxies is far, far away, about 450
million light-years from planet Earth [6] and cataloged as galaxy cluster
Abell S0740. Dominated by the cluster's large central elliptical galaxy (ESO
325-G004), this reprocessed Hubble Space Telescope view [7]  takes in a
remarkable assortment of galaxy shapes and sizes with only a few spiky [8]
foreground stars scattered through the field. The giant elliptical galaxy [9]
(right of center) spans over 100,000 light years and contains about 100
billion stars, comparable in size to our own spiral Milky Way galaxy [10] .
The Hubble data can reveal a wealth of detail [11]  in even these distant
galaxies, including arms and dust lanes, star clusters, ring structures, and
gravitational lensing arcs [12] .
